It was a full moon. Sirius was trying to control his shift into Grimm, but he couldn't seem to control it.

He kept telling you over and over again to run before he shifted because he didn't want to hurt you while Grimm was in control.

But you kept refusing. You didn't want to leave him in a time of need.

You had read many guides on how to control a violent animagus and had a few ways to get him in control of Grimm.

The moon was creeping up slowly, He was running out of time.
